A laboratory bearing test rig was constructed to study wear in three high speed roller bearings simultaneously under different conditions of loading and lubrication. A test run of 355 hours duration was performed during which wear of bearings was monitored using DR ferrography. The test bearings from the rig were examined using metallography and microhardness measurements. Wear debris particles were collected from oil samples using ferrography. These were studied using bichromatic microscopy, scanning electron microscopy and energy dispersive x-ray analysis. The results of ferrography were correlated with the metallographic results.
